Now, let’s dive into the heart of the matter—how to bring this dish to life. Follow these steps, and your kitchen will soon be filled with the tantalizing aroma of this delightful creation:

1. Heat the olive oil in a large skillet over medium heat. Add the sausage, breaking it apart with a wooden spoon as it cooks. Once browned and cooked through, remove the sausage from the skillet and set aside.

2. In the same skillet, add the minced garlic and diced onion. Sauté until the onion becomes translucent and the garlic is fragrant, a scent that always transports me back to Nonna Rosa’s bustling kitchen.

3. Stir in the diced bell pepper, allowing it to soften slightly. Then, return the cooked sausage to the pan.

4. Add the can of diced tomatoes, along with their juices, and bring the mixture to a simmer. This is where the magic starts to happen, as the flavors meld together beautifully.

5. Pour in the heavy cream, stirring gently to combine. Allow the sauce to simmer until it thickens slightly, about 5 minutes.

6. Gently fold in the cheese tortellini, ensuring each piece is well-coated in the creamy sauce. Cover the skillet and let it cook for about 5 to 7 minutes, or until the tortellini is tender and warmed through.

7. Just before serving, stir in the fresh spinach leaves and oregano, letting the residual heat wilt the spinach.

8. Season with salt and freshly ground black pepper to taste. Serve with a generous sprinkle of grated Parmesan cheese, and savor the moment.
